cgidesign Posted March 19, 2021 Posted March 19, 2021 I have a 32 bit exr render test image open in Photo 1.9.1 I like to add a curves adjustment. But as shown in the screenshot that does not work because the data is compressed at the right side of the graph. According to Serif the adjustments work in 32 bit mode - so, I assume I am making a mistake. Hope, somebody can give a hint.
NotMyFault Posted March 20, 2021 Posted March 20, 2021 Hi, curves work perfectly on my Windows PC with 32-bit images. You may have a look to the excellent tutorial: Goodby Forum, thanks for good discussion and so much support from great peers and Affinity staff. It was a great pleasure to be part of this fantastic community. After 03.10.2025 find me on https://creofora.com
cgidesign Posted March 24, 2021 Author Posted March 24, 2021 Thanks for chiming in. I have seen the video in the past. But it does not cover the detail I am asking about. I loaded an exr strait out of a renderer. No tonemapping etc. Goal is to edit the file in its original hdr range. Issue seems to me, that Affinity does not scale its tools, graphs according to the value range in the incomming image. As you can see, the curves, scopes show data only at the extremes. I can't edit with the curves because all data is within an area of maybe 2 mm edit space.
